Jordan, To add a few comments about your list of 8/5: 1. American Crows occasionally make some raven-like sounds but they can be differentiated with care. 2. The chickadees you saw were Carolina Chickadees not Black-caps. 3. Your reddish sandpiper was almost certainly a juvenile Least. Brown's Bridge has been underreported this season. I hope you continue to get out there. Bob Ringler
